[Previous Technology] Liquid crystal displays (LCDs) have a small size and light weight, which makes them extremely advantageous in the market for portable display devices and small space applications. Thin film transistor liquid crystal display (Thm Film Transistor Liquid Crystal Display, TFT-LCD) is one of the most noticeable components in liquid crystal display products in terms of performance and display effect. Its working principle is based on the field effect transistor to grasp the liquid crystal film.

Referring to the third figure, a schematic diagram of a circuit arrangement according to a preferred embodiment of the present invention is shown. According to this embodiment, the main feature of this case is the arrangement and design of the circuit circuit, which includes a -Gamma power circuit 3G4 (Gammap. Er⑽Uit). -VDD 30 (V () ltage drain drain) and -Ground circuit 300 (GroUnd circuit, GND) are arranged on the plurality of first flexible circuit boards 212 and the glass substrate 214, and are electrically connected respectively A drive signal circuit (not shown) is connected to each drive integrated circuit chip 206 in each of the drive integrated circuit chips 206 for transmitting a drive signal 220 (see the second figure), The plurality of driving integrated circuit chips connected to the driving signal line are connected to each other in series to transmit and display signals. It is worth noting, however, that other forms of circuit layout can also be used in the present invention. The electric power of the present invention is transmitted in a sequential manner to the driving integrated circuit chip 206 located in the X direction, in other words, this electric power is transmitted one by one by the printed circuit board 2 in the X direction. It is transmitted to all driving integrated circuit chips 206 in the X direction. Please refer to the second figure again. The transmission of the X-direction driving signal 22 in the present invention is also transmitted in a sequential manner to the X-direction driving integrated circuit chip 206 to control and drive the integrated circuit chip to the panel. Show 9 594323 = like. It is worth noting that the circuit architecture of the present invention can also be applied to the printed circuit of gamma " to transmit scanning signals to reduce its volume. The power transmission circuit of the present invention is respectively laid on the weighted circuit board 212 and the glass substrate 214, and the power is supplied to the X direction to drive the integrated circuit chip dove by serial transmission. Because: the glass substrate has a The large resistance causes pressure in the process of power transmission: 'change ... the power supply of each driving integrated circuit chip' will gradually decrease with the power transmission. Therefore, in order to avoid the difference in power, the image Distortion. The present invention can also add a voltage stabilizing device to the conventional integrated circuit chip to stabilize the output voltage. Refer to Figure 4A: It is not a schematic diagram of a conventional drive integrated circuit chip, including a bidirectional offset register 40, a temporary storage of data 2; a holding circuit, a level offset circuit 404, and a digital / analog converter 4 5 and the output circuit 406. In order to stabilize the output voltage of the present invention, a voltage shifter technique is added to the conventional driving integrated circuit chip to stabilize the output voltage. Refer to Figure 4B for a schematic diagram of the driving integrated circuit chip used in this application. . On the other hand, according to the wiring arrangement method of the present invention, the width of the narrow margin required by the glass substrate can be reduced by reducing the distance between the first flexible circuit board carrying the driving integrated circuit chip, because the Part of the circuit is arranged on the glass substrate, and usually the glass substrate has a large resistance. 'In order to avoid causing excessive voltage drop, it is generally possible to reduce the resistance by widening the area of the circuit', but this method will increase the glass substrate. Required narrow forehead width. Therefore, the present invention reduces the distance between the first-flex circuit boards carrying the driver integrated circuit chip, and reduces the length of the lines arranged on the glass substrate 10 594323 to reduce the voltage drop, so the circuit area can be reduced, and the narrow forehead can be reduced. width. "To sum up, the present invention re-arranges the traditional arrangement of printed circuit boards and the power transmission lines on the human circuit board and the glass substrate equipped with the driver integrated circuit chip to reduce the overall liquid crystal display volume. On the same day, the invention also added a voltage stabilizing device to the conventional dynamic integrated circuit chip to stabilize the wheel-out voltage to avoid distortion of the image screen.
